DNA is a molecule that makes people unique in this world. DNA testing was discovered by Prof. Alec Jeffreys of Leicester University in 1984. At this time the first test was done. When two fingerprints are compared you usually check the loops and whorls of the fingerprints. Same is the case with DNA testing. In DNA testing different features of DNA are compared. These DNA features are called DNA markers.

If you get to know that the DNA markers of the two compared DNA are totally similar then it is the possibility that they can come from the same person. If the DNA markers are not totally identical but there are some markets that are matching then you can conclude that there is some relationship between two persons. The degree of the similarity between DNA profiles is a representation of the degree of relatedness between people.

DNA testing is done for many different cases. The most important two cases are identification between two individuals and the second one is that the stain in the crime scene has to match with the suspect. First time DNA testing was done for non criminal and legal cases like immigration and child support cases. In 2004 more than 7000 DNA tests were taken in UK only to check the relationship.

DNA testing is best in determining the relationship between two individuals. It is an unquestionable proof of relatedness. The first time DNA testing was done in a landmark immigration case in 1985. It is Sarbah vs. Home Office case. It is a mother son case in which DNA testing is done to prove the reliability of the relationship between mother and son.

Child Support Agencies also use DNA testing to check who are the mother and father of child. There are many different DNA codes like AATTGCCTTTTAAAAA. Codes are passed on to the child from parents. Everybody has different code.

Everything has been changed just by the discovery of one small thing that is DNA. Now it is very easy to solve the legal and criminal cases.

As a father who wants certainty to father a child with unknown existence, you may want to submit yourself through a dna testing. In this way, you are guaranteed that the child is really yours. Or you may want to try testing for paternity.
